What is a watershed?
A: a building for water storage
B: the land area that drains to a given water body
C: a shack from which fishing occurs
D: a moment in time when you cross into a new area
E: a new way of organizing environmental agencies
Urbanization results in
increased surface runoff
At ~10% impervious we begin to see:
Large Conventional BMPs
LID Site Design
Objective - to provide a process by which LID is considered at an early stage in the planning process to prevent stormwater impacts rather than mitigate them.
Goal: Reduce the amount of surface runoff by reducing impervious cover and preserving natural areas
Rely on small, distributed on-site practices
Infiltrate or reuse as much as possible; filter before discharge
Source controls to minimize pollution
Stormwater is a resource
There are many…
